(or. 292 s57) 2 Claims.

This invention relates to a modified or improved form of escutcheonplate fastener, the improvement being on my former patent, No.1,653,513, issued December 20, 1927, and entitle Escutcheon platefastener.

The object of the present invention is generally to improve and simplifythe construction and operation of fasteners of the character described;to provide a mechanism which permits an escutcheon plate to be readilyand quickly attached to a door lock and rigidly secured when applied; toprovide a mechanism which also permits easy removal of the escutcheonplate for inspection, repair of a door lock, etc.; to provide amechanism which eliminates the use of exterior screws and like fasteningmeans; and furthenand more specifically stated, to provide one or moreresilient springs or latches which engage the peripheral edge of theescutcheon plate to secure it in place.

The invention is shown by way of illustration in the accompanyingdrawings, in which:

Fig. 1 is an edge view of a door showing a lock installed therein, saidview being partially in section to show the application of theinvention;

Fig. 2 is a perspective view of a laminated clamping plate;

Fig. 3 is a perspective view of one of the escutcheon plates;

Fig. e is a perspective View of the clamping plate shown in Fig. 2, butshowing the inner plate removed;

Fig. 6 is a perspective View of the outer plate of the clamping plate;

Fig. 7 is a perspective View partly broken away showing a modified formof laminated clamping plate;

Fig. 8 is a side elevation of Fig. '7;

Fig. 9 is a perspective view showing another modified form of laminatedclamping plate; and

Fig. 10 is a side elevation of Fig. 9.

Referring to the drawings in detail, and particularly Figs. 1 to 6,inclusive, A indicates an ordinary door, 2 a latch plate, 3 the latchbolt, by which the door is locked or unlocked, 4 the lock housing, 5 andt the exterior escutcheon plates enclosing the look housing, 5 thespindle oi the lock, and 8 the knobs which are applied to the spindle.The escutcheon plate 5 is in this instance permanently secured to thelock housing 4; hence, when the housing 4 is inserted in the door, aclamping plate, generally indicated at B and forming a part of thehousing, must be applied to the inner face of the door, and screws 9passing through the clamping plate and having threaded engagement withthe housing must also be employed in order to secure the lock housing inthe door and to pull the escutcheon plate 5 snugly up against the outerface of the door.

The clamping plate used in the present instance is laminated instructure to provide rigidity and strength, and to form a housing orholder for one or more resilient latches or fasteners hereinafter to bedescribed.

The clamping plate is covered or enclosed by the escutcheon plate 6, andthe fasteners just referred to serve the function of securing theescutcheon plate 6 when applied and are at the same time constructed topermit ready removal of the escutcheon plate if the lock is to beinspected, repaired,'or the like.

The clamping plate and the escutcheon plate to be secured thereto arebest shown in Figs. 2 to 6, inclusive. The clamping plate is laminatedin structure and consists of an outerplate It, an intermediate plate H,and an inner plate i2. The outer plate I ll is provided with an annularflange [to within which the plates It and i2 nest. The flange is cutaway as at liib to form a pair of opposed openings through. whichfasteners or latches are projected, as will hereinafter be de' scribed.A central opening tile is formed in the plate [0 to permit it to slipover the spindle of the look when applied thereto, and a pair of tubularrivets llld are formed in the face of the plate I0, and these, or a hubsuch as shown at Me in Figs. 1 and 2, serve to unite and secure theseveral laminations forming the clamping plate.

The intermediate plate I I is circular to fit within the flange Illa ofplate I t. It is perforated as at I la to permit the tubular rivets [lidto pass therethrough, and it is cut away as at l lb to form a pair ofsaddles which support a pair of springs [4, said springs beingsubstantially U-shaped at their center portion to permit the roundedends thereof to project through the openings [0b formed in the flange ofplate It.

The inner plate I2 is circular to fit within the flang Ida of the outerplate. tI has a central opening 521) and it is perforated as at toreceive the tubular rivets lild see (Fig. 6) and to permit said rivetsto be flanged or riveted over as shown in Figs. 8 and 10 when the threeplates are assembled. The inner and outer plates retain or form ahousing for the springs [4, while the intermediate plate forms astiffener for the inner and outer plates and a saddle for the support ofthe springs.

The escutcheon plate 6, which is applied to cover the laminated clampingplate, is provided with an annular flange 6a which telescopes over theflange lfla of the plate Ill. Two openings 61) are formed in the flange6a, and these openings receive the rounded ends of the springs orfasteners I4, thereby releasably securing the escutcheon plate whenapplied,

In actual practice, when the lock is inserted in a door as shown in Fig.1, it is secured by applying the clamping plate B to the inner face of adoor and then inserting and tightening the screws 9. Thereafter theescutcheon plate 6 is slipped over the spindle and flange 6a will thustelescope over the clamping plate. It being understood that thefasteners, or in other words the rounded ends of the spring M, are firstdepressed to permit application of the escutcheon plate; then, byrotating the plate 6 until the opening 6a registers with the springs,these will automatically project into said openings and thereby securethe escutcheon plate. To remove the escutcheon plate, it is onlynecessary to grasp and slightly rotate the same as such rotation willcause depression of the rounded ends of the springs, and thereby releasethe plate and permit its removal. Thus the plate is readily applied andis just as readily removed when necessity demands.

In Figs, '7 and 8, a slight modification of the laminated clamping plateis shown. The only difference is in the shape of the cut away portion I6of the intermediate plate and the shape of the spring or fastenerindicated at H. In Figs. 9 and 10 another modification is shown. In thisinstance the intermediate plate is cut away to form a pocket 18 and twolugs l9 to form a support for a flat spring 20. This spring, in turn,actuates a depressible latch 2| which is adapted to enter the openingformed in the annular flange of the escutcheon plate.

In the modifications shown in Figs. 7 and 8, it should be understoodthat there are a pair of fasteners disposed opposite to each other, andthe same is true of the latches 2|, shown in Figs. 9 and 10, and whilethis and other features of the invention are more or less specificallyillustrated I wish it understood that various changes in form andproportion may be resorted to within the scope of the appended claims;similarly that the materials and finish of the several parts employedmay be such as the experience and judgment of the manufacturer maydictate, or varying uses may demand.

Having thus described my invention, what I claim and desire to secure byLetters Patent, is:

1. In a door lock of the character described, a clamping plateconsisting of an outer, an intermediate and an inner plate, meanssecuring said plates together as a unit, an escutcheon plate forming acover for the clamping plate, an annular flange on the escutcheon platetelescoping over and covering the peripheral edge of the clamping plate,and spring actuated means carried by the intermediate plate of theclamping plate projectable into retaining means formed in the annularflange of the escutcheon plate to retain it against removal.

2. In a door lock of the character described, a clamping plateconsisting of an outer, an intermediate and an inner plate, meanssecuring said plates together as a unit, an escutcheon plate forming acover for the clamping plate, an annular flange on the escutcheon platetelescoping over and covering the peripheral edge of the clamping plate,a pair of opposed pockets formed in the intermediate plate of theclamping plate, a spring in each pocket and retained therein by theouter and inner plates of the clamping plate, and a rounded portion oneach spring projectable from the peripheral edge of the clamping plateinto engagement with the annular flange on the escutcheon plate tosecure it against removal from the clamping plate.
